What's this? Cassandra de Vries has a conscience? The Skedar say "Yummy
conscience, Ms. De Vries." Now you're on your own against the reptilians.
Flip that Knife around to make it poisonous and throwable, then exit your
cell and take down the first Skedar you come across. He will take a moment
to die as the poison slowly takes effect. Grab the Mauler from the fallen
beast, and creep around the corner to the left. Smoke the other Skedar here
with the Mauler.

Then head down the ramp next to the elevator. At the bottom is a room with
three alien computer displays. Take them down with the Mauler, completing
the objective.

2. Access navigational systems

Take the elevator up to the main hangar of the attack ship. In the next hallway,
you'll meet up with Elvis. Dude, what's up with the vest? Elvis will hand
you the AR34. Up the ramp, you'll encounter a skirmish between Maians and
Skedar. You can either help with the fight, or run like a coward to the elevator
at the back of the room.

Perfect
objective: Open hangar doors

In Perfect, you won't encounter Elvis until you do an extra objective. Head
up the ramp and across the room to another ramp. Go through the door here
and ride the lift up to the control room. Kill the Skedar here. Go to the
hangar door controls and press the button to fulfill the objective.

In the main hangar, go to the blue elevator doors at the rear of the craft.
Ride it up to the upper levels.

When you exit, head forward and take down the Skedar through the first set
of doors. The charged-up Mauler is a good bet for one-shot kills. Head through
the next door to the right, killing the Skedar and claiming the Shield on
the table. Take the only other door in this room to a narrow chamber separated
by a central structure. On the far end is a Skedar laying in wait. Maul him
and go through the door straight ahead. After this chamber, take a left,
finding yourself in the Skedar navigation room. Keep the Skedar at bay while
Elvis does the business on the nav system. Objective complete.

3. Sabotage
engine systems

Go through the passage on the other side of the room. There is a Skedar around
the corner to the right. Creep around the corner and level him with a charge-up
shot. Follow the winding ramp up, smoking Skedar as you proceed. Eventually
you'll pass an up-sloping ramp to the right. Step through the next set of
doors into a big area. The doors on either side of this room lead to identical
passages on either side of the ship. Head through one of them, tracking through
the passages until you find the engine room.

There are tons of Skedar guarding this room. Pause at the entrance, darting
into view and shooting with the Mauler, then strafing back to grab some cover.
When the engine room is devoid of enemies, aim at the two brackets surrounding
the engine core. Fire on them until they shatter, then retreat down the hall
and wait for the explosion.

4. Gain
control of bridge

Return to the small side ramp that you past earlier (just past the blue-green
doors). Climb the ramp, admiring the space view. When you reach a large turquoise
door, head through on your way to the bridge.

Through the next door, you'll meet a couple more Skedar. Maul them royally.
Climb to the top of this room and through the door. Elvis runs away, saying
he'll meet you in a bit. Take a couple of elevators up to the bridge.

When the doors open, shoot the Skedar atop the bridge directly ahead. He
will drop a Double Mauler (hidden item). Then kill the two on either side.
When they drop, head up the circling ramp and position yourself facing the
door. Skedar will continue to come in through this elevator door until the
objective is complete. Really all you have to do is stay alive.
